It is shown that the coherent electron-pair production by very-high-energy photons in a crystal converter could be used in order to obtain a cleaner electron beam from the CERN SPS or Batavia 400 GeV proton synchrotron. Coherent electron-pair cross section in a tungsten crystal has been integrated over the photon energy spectrum which fits the inclusive reaction ISR data. Performances of several crystals have been evaluated before selecting the tungsten one.

Abstract
It is shown that the coherent electron-pair production by very-high-energy photons in a crystal converter could be used in order to obtain a cleaner electron beam from the CERN SPS or Batavia 400 GeV proton synchrotron. Coherent electron-pair cross section in a tungsten crystal has been integrated over the photon energy spectrum which fits the inclusive reaction ISR data. Performances of several crystals have been evaluated before selecting the tungsten one.
